Hyper-v workloads are not supported by Oracle Cloud VMware Solution, as they are based on Microsoft's hypervisor technology, which is different from VMware's ESXi hypervisor4

In OCI a budget can be used to set soft limits on your Oracle Cloud Infrastructure spending. You can set alerts on your budget to let you know when you might exceed your budget, and you can view all of your budgets and spending from one single place in the Oracle Cloud Infrastructure console.

Budgets are set on

* Cost-tracking tags

* Compartments (including the root compartment)

Budget is the OCI capability that allows you to set up alerts to notify you if a budget forecast exceeds or spending surpasses a certain amount. You can create budget alerts based on actual spending or forecasted spending, and specify the percentage or amount of the budget that triggers the alert. You can also choose how to receive the alert notifications, such as email or OCI Notifications service.

You can create and manage resources in the following ways:

Oracle Cloud Infrastructure Console The Console is an intuitive, graphical interface that lets you create and manage your instances, cloud networks, and storage volumes, as well as your users and permissions. SeeUsing the Console.

Oracle Cloud Infrastructure APIs The Oracle Cloud Infrastructure APIs are typical REST APIs that use HTTPS requests and responses. SeeAPI Requests.

SDKs Several Software Development Kits are available for easy integration with the Oracle Cloud Infrastructure APIs, including SDKs for Java, Ruby, and Python. For more information, seeDeveloper Resources.

Command Line Interface (CLI) You can use a command line interface with some services. For more information, seeDeveloper Resources.

Terraform Oracle supports Terraform. Terraform is 'infrastructure-as-code' software that allows you to define your infrastructure resources in files that you can persist, version, and share. For more information, seeGetting Started with the Terraform Provider.

Ansible Oracle supports the use of Ansible for cloud infrastructure provisioning, orchestration, and configuration management. Ansible allows you to automate configuring and provisioning your cloud infrastructure, deploying and updating software assets, and orchestrating your complex operational processes. For more information, seeGetting Started with Ansible for Oracle Cloud Infrastructure.

Resource Manager Resource Manager is an Oracle Cloud Infrastructure service that allows you to automate the process of provisioning your Oracle Cloud Infrastructure resources. It helps you install, configure, and manage resources using the 'infrastructure-as-code' model. For more information, seeOverview of Resource Manager.

To design a high availability architecture, three key elements should be considered--- redundancy, monitoring, and failover:

1) Redundancymeans that multiple components can perform the same task. The problem of a single point of failure is eliminated because redundant components can take over a task performed by a component that has failed.

2) Monitoringmeans checking whether or not a component is working properly.

3) Failoveris the process by which a secondary component becomes primary when the primary component fails.

The best practices introduced here focus on these three key elements. Although high availability can be achieved at many different levels, including the application level and the cloud infrastructure level, here we will focus on the cloud infrastructure level.

An Oracle Cloud Infrastructureregionis a localized geographic area composed of one or more availability domains, each composed of three fault domains. High availability is ensured by a redundancy of fault domains within the availability domains.

Anavailability domainis one or more data centers located within a region. Availability domains are isolated from each other, fault tolerant, and unlikely to fail simultaneously. Because availability domains do not share physical infrastructure, such as power or cooling, or the internal availability domain network, a failure that impacts one availability domain is unlikely to impact the availability of others.

Afault domainis a grouping of hardware and infrastructure within an availability domain. Each availability domain contains three fault domains. Fault domains let you distribute your instances so that they are not on the same physical hardware within a single availability domain. As a result, an unexpected hardware failure or a Compute hardware maintenance that affects one fault domain does not affect instances in other fault domains. You can optionally specify the fault domain for a new instance at launch time, or you can let the system select one for you.

All the availability domains in a region are connected to each other by a low-latency, high bandwidth network. This predictable, encrypted interconnection between availability domains provides the building blocks for both high availability and disaster recovery.
